Fix demo family generation: add diverse events and fix missing event references

- Added 12 different event types (Baptism, Education, Occupation, etc.)
- Fixed missing event references by storing and reusing original events
- Made event generation deterministic with random seed
- Updated gen_person to return both XML and tuple format for event reuse
- All event references now properly defined and validated
- Demo family now includes 240+ additional events for comprehensive testing
